Specification of Letters Patent.

Application led May 20, 1910. Serial No. 562,530.

To all whom it may concern.'

a citizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented a new and usefulPackage-Forming Machine, of which the following is a specification insuch full and clear terms as will enable those skilled in the art toconstruct and use the same.

This invention relates to a raisin weighing, packing and carto-n fillingmachine, and its object is to weigh definite quantities of looseraisins, place a wrapper around the quantity of raisins weighed, closethe wrapper over the raisins package and insert the package in an opencarton. All the folding and packaging mechanisms being set in motion bythe weight of the body'of raisins to be packed.

A further object of the invention is to produce a machine which will beoperated by power merely upon the necessary quantity of material beingplaced upon the platform.

Another object of the invention is to produce a machine for weighing andpackaging materials which do not readily form packages of themselves,but which must be pressed into -a package.

Another object of the invention is to produce a machine which is capableof using one strip of paper to Wrap the mass of fruit in, the paperbeing cut into suitable pieces and passed entirely around the package,or separate sheets may be used i-n the machine if so desired.

, Other objects of the invention will appear as the descriptionproceeds.

In the drawings in which the same numeral of reference is applied to thesaine portions throughout the several views, Figure l is a sideelevation of the machine, Fig. 2 is a plan view of the machine, Fig. 3is an end elevation of the machine looking from the right of Fig. 2.Fig. 4 is an end elevation of the machine looking from the left of Fig.2. Fig. 5 is a vertical sectional view through the package feedingplunger and weighing chamber. Fig. 6 is a side elevation of the foldingmechanism showing the weighing table support S remove from the machine.Fig. 7 is a view in section on the line 7--7 shown in Fig. 6, a

portion of the guide flanges on the side plate 3 being shown.

c It will be understood by those skilled in the art that it is quiteditiicult to weigh and package raisins or other sticky fruit of thischaracter, for the reason that the pieces of fruit become gummed to theortions of the weighing machine, or portions of the packaging machinewith the result that the apparatus is quickly thro-wn out of commission.With this invention the fruit does not come into direct contact withanypart of the machine, save the feedin hopper, all other parts beingcovered by oiled paper Patented Feb. 4,1913.

which is wrapped about the mass of fruit.

naled.` These two side frames are secured together by means of a squareframe 4 eX- tending across the top ofthe machine and in which thefeeding hopper 5 is placed, said feeding hopper having a cored outportion 6. therearound to supply steam for heating the same. Thisfeeding hopper has gates 7 and 8 operating in aslide 9. The .gate 7 isconnected' to a lever 9 and the gate 8 is connected to a lever 10,saidlevers being pivoted at 11 and 12 respectively on the frame 4,.saidpivots having levers 13 and 14 connected therewith, a link 15connecting. the levers 13 and 14. Connect-ed to the lever 9, below thepivot point thereof, is a bar 16 havin a fork 17. i This bar 16 isconnected with a bell crank lever 18 which is pivoted on the frame 4 at19, said bell crank having a downwardly ext-ending bar 20 connectedthereto. The bar 20 extends down from the bell crank lever 18 through anopening in the base of the machine and it is provided with a pin 2l forthe purpose of opening the gates in the bottom of the feeding chute. Thebar 16 operates to close said gates when a charge of fruit has beendelivered to the packaging. apparatus in a manner to be explained later.

The weighing table 22 is supported by means of a long rod 23, whichlatter is in turn supported by the weighing lever 24, said weighinglever having a steel insert 25 to bear on the steel knife edge 26 tomake the least possible friction therewith.

Extending outwardly from the machine at an angle of about 45 degrees tothe horizontal, see Fig. lisa weight carryingpbar 24 on which the Weight27 is supported, said weight being of such size as to move when thedesired quantity of fruit has been placed on the weighing table. The bar23 is pivoted to the Weighing table 2 2, and in order that the lattermay move as easily and freely as possible in the compartment in which ittravels, it is provided with four antifriction wheels 28, which areplaced near the cent-er of the weighing table, and on the other twosides of the weighing table four anti-friction wheels 29 are journaled.The

eight wheels insuring the easiest possible movement of the weighingtable, in the sage way in which it travels.

The weighing table moves from the position shown in Fig. 5 to theposition indicated in dotted-lines below, in which latter position thebody of fruit is formed into a package and has the oiled paper wrappingfolded around the same.

Secured on' the frames 2 and 3 are two arms 30 and 31, each supportingthe roll of paper 32, said roll of paper having the sheet passing undera guide roll 33, journaled in the frame 4 above the frames 2 and 3. Fromthis point the paper passes between two rolls 34 apd 35 journaled onshafts 36 and 37 respectively. The roll 34 being adjusted in itsbearings by means of set screws 38 which regulate ythe pressure o-f theroll 34 on the paper. @ne of said rolls has a friction surface of cloth,rubber or the like.

pas-

The paper feed rolls are driven one complete t urn at a time by means ofa gear 40 in mesh with the gear 37, the cycle of operations of which isto be explained later.

Journaled on the upper part of the frame 4 is a shaft 41 which isprovided with a lever 42 connected to a link 43 which is raised by meansof a roller 44 on the gear 40, said shaft 41 having two arms 45` at thefree ends of which knife holders 46 are supported, said arms' being heldin a fixed position by means of a small shaft 46. The knife holders 46rest on flat springs 47, said flat springs serving to hold the knife inthe raised position, after the paper has been cut. Attached to the knifeholders 46 is a knife 48 which coperates with a fixed knife 49 to cuto6' the desired amount of paper required for each weighed quantity offruit.

p Journaled in the frames 2 and 3 is a shaft 50 which shaft has securedthereto a presser plate 51 which operates to press the oiled paper downon the body of the fruit and to form one side of the compartment inwhich the mass of fruit collects on said paper. This shaft is alsoprovided with a crank 52 connected with a link 53 which latter isconnected to an arm 54 freely movable on the shaft 55. The bossconnected with said ipaaooe grooved' cam 57 on the shaft 58.- Thisgrooved cam has a projection 59 which operates on the rotation of theshaft 58 to canse the presser plate 51 to move through an arc of 90degrees, pressing the paper down against the body of raisins on theweighing table which latterl has then been forced by the weight of thefruit to its lowest position as indicated by the dotted lines on Fig. 5,the plate 51 immediately rising to its original position and being heldthere by the grooved cam 57.

Journaled in the side plates 2 and 3 on the opposite side of the tablefrom the shaft 50 is a shaft 60, and loosely journal'ed on the shaft 60is the folder plate 61, said plate having upstanding slotted ears 63 atthe oposite edges thereof. Keyed to said shaft 60 are two arms 64 whichhave a folding point 64 to complete, the operation of the folding of thepaper around the ends of the package. Each arm 64 is provided with a pin62 which extends through the slot in the ear 63, the object being topermit the arms 64 to move back out of the way of the incoming sheet ofpaper and to hold the plate 61 against the table from which the paper isfed over the weighing compartment. The operation of this folder will berst, to press down on the paper and cause it to be pressed across theend of the package. When the plate Gltouches the top of the fruitpackage the arms 62 will continue their rotation until they have movedslightly more than 9() degrees, and have their points 64 extendingacross each end of the package tucking the paper down.

Immediately below the shaft 60 there is a shaft 67 also journaled in theside frames 2 and 3. This shaft carries rigidly therewith two tuckingplates 68, each of which has a depending projection 69. These twotucking plates and the two tucking plates 64 cover about one-half of theend of the package and fold the top and bottom respectively of the paperacross the ends of the body of fruit.

The frame 66, of which there is one slidable in each of the plates 2 and3 is provided with a projecting point 70 which covers the portion of theoiled paper package at the right hand edges thereof, see Fig. 1, betweenthe two plates 64 and 68. This plate 66 has an upwardly extendingportion 7l which cooperates with the depending projection 69 on theplate 68 to raise the latter into contact with the plate 64 when theplate 66 has been pushed forward, a roller 71 lifting the arm 68 ontothe portion 71..

Tt is to be noted that the folding mechanism is duplicated at each endof the formed package. This plate 66 is alsoy provided with teeth 72which copcrate with the teeth on the boss 73 to push forward the finaltucking plate 74. The plate 74 has a projecting pin 74 which operates ina slot in an arm 73 secured on the shaft carrying the boss 73. The plate66 is pushed forward by means of a link 7 5 which is pivoted thereto andwhich is driven by means of a crank 76 on a shaft 77, said shaftcarrying.the gear 40 and a small gear 78 in mesh with the larger interruptedgear 79 on the shaft 80.

The shaft 80 is journaled in the plates 2 and 3 and is parallel to theshafts 77, 37 and 36. It will be observed that the* gear 79 hasprecisely the samenumber of teeth as the small pinion 78, the remainderof said gear being cut-away so that upon o-ne Vso rotation thereof thegear 78 will be rotated one complete turn only. It will also be observedthat the gear 40 has the same number of teeth as each of the gears 36and 37', the result of which will be to drive the gears 36 and 37 onecomplete turn upon one rotation of the gear 40. Secured to the shaft 80under the .gear 40 is a bevel wheel 81 which is driven by means of abevel gear 82 on the shaft 58, said shaft being journaled in boxes 83and 84,' secured to the said plate 3 extending longitudinally thereof.

Immediately below the shaft S8-and parallel therewith is a shaft 85journaled in boxes 86 and 87, said shaft having a gear 88'which has thesame number of teeth as the gear 89, on the shaft 58. The shaft 85carries a disk 90 having a pin 91 therein which is connected to a link92, the opposite end of said link being co-nnected at 93 to a lever 94,said lever being pivoted at 95 to the base 1 of the machine. rlhe upperend of this lever 94 is pivotally connected to a link 96 which latter ispivotally connected at its opposite end to a plunger 97, said plungerhavingubstantially 'the same cross section as the cross section of thepackage to be formed. This plunger 97 is movable in a slide box 98,which slide box note Fig. 5, is secured to the frame 3 at the same levelas the top of the table when the package has been formed. Immediatelyopposite the plunger 97, the frame 2 is provided with an opening 99through which the plunger pushes the package of fruit after theoperations have been completed.

Secured on the base 1 and at a short distance from the plate 2 is a sideplate 100 said plate having bearings for the shafts 36 and 37, and for ashaft 101, which latter has a bearing 102 in the plate 2. This plate hasa bed 103 with grooves 104 and 105 therein, said grooves being for thereception ofchains 106 and 107, passing over sprockets 106 and 107.Secured to these two chains,

- which are parallel to each other are a plurality of carton holdingboxes 108, each of said boxes having two pins 109 to hold the iiaps 110of the carton 111 open while moving through the machine. It will also beobserved that the plate 103 is cut-away at 112 to permit the dependingleaf 113 of the carton 111 to extend downward during the pas sage of thebox through the machine, the upper leaf 114 of the box pressing againstthe side frame 2.

Since the empty packages are to be fed continuously to the machine bymeans of chains104 and 105, mechanism for moving one empty package intothe vplace previously occupied by the filled package must be provided,and the movement must be accomplished during some time in which theplunger 97 is either stationary or moving away from the carton. Now, itwill be observed that the paper feeding operation will be accomplishedduring the time in which the ends of the package are being folded, andbefore the plunger starts on its journey to press the package into thecarton, therefore, the box must be moved during the period of rotationof either of the rolls 34 or 35, and since the two shafts move inopposite directions, they form convenient means for discharging thecartons in one direction or the other, as may be desired.

The shaft 101 is provided with two sprocket driving gears 106 and 107and on its outer end it has a gear 126 which is driven from a gear 127on the projecting end of the shaft 36, or, if desired, from theprojecting end of the shaft 37, the lat-ter gear being small enough todrive the chains 104 and 105 just the distance from center to center oftwo cartons, the chain driving the gear 126 from the gear 127.

The Ashaft 58 is provided with a slidable collar 115, which collar has aclutch point to connect with the clutch 116 on the boss on the pulley117. The slidable collar is operated by means o-f a lever 118 having afork extending over the collar 115, said lever being pivoted to theframe 3 and 119. The opposite end of this lever has-a latch 120 pivotedthereto, the object being to throw the machine into gear when the bar 24comes into contact therewith, and should the bar 24 accidentally passthe latch 120 it will permit the bar 24 to return to its initialposition without interference.

The clutch on the collar 115 is provided with but a single point 121which coperates with a single point 122 on the boss of the drivingpulley 117. After the clutch has made one complete turn, the clutch isdisengaged by the projecting point 123 on t-he boss of the pulley 117striking an`oppositely placed point 124 on t-he lever 118 which forcesthe collar 115 away from the hub of the driving pulley and disengagesthe clutch.

In order that the bar 24 may not tip over on one side 0r move out ofplace, a slotted plate 129 is secured on the knife bar 26 by means of aset screw130 anda hole is drilled in this slotted plate to hold a ball129 to bearon the side of the insert- 25 in said bar, one of theseplates being placed on each side of said bar 24. lt will, of course, beunderstood that these balls touch the insert 25 very lightly'and offerpractically no resistance to the movement of the bar 24, but do preventit from mov'ing away from its proper position.

The cycle. of operations of the machine is as follows: Starting from theposition of\ rest shown in Fig. 1, a piece of pa er having been placedunder lthe hopper or feeding the fruit, the latter is permitted to fallon the paper, and` since the paper is very pliable, the weight of thefruit is immediately carried by the table 22 of the weighing apparatusand as the weight increases to such a point as becomes sufficient toraise the weight 27, the table22 descends to the bottom of thecompartment in which it moves. As soon as. the bar 24 strikes the latch120, and fork 17 both of which operations occur at substantially thesame time, the machine is thrown into gear and will start when thepoints l121 and 122 meet, and the supply ofV fruit is cutfod by theclosing of the gates 7 and 8. fThe machine is now running to form andfold the package. The first operation whichtakes place. is the throwingover of the roller 56 by theg high place of the cam 57. rlfhis causesthe presser plate l51 which operates to fold one side of the paper downover the fruit toI firmly press the latter into the desired conditionfor insertion in the bok. This presser. plate is immediately returned toits initial position by the cam 57 and throughout the remainder of thecycle of operations this. plate continues in the same position. Now, itwill be observed that the bevel wheel 82 during this time is driving thebevel wheel 8l lon the shaft 8O and the gear 79 is driving the gear 78,therefore, the slide 66 is in process of being pushed forward by thelink 75. rfhe cam 71 on said slide pushing the folder plate 68 up duringthe same time that the plate 51 is pressing down on the fruit, thus thepackage is more conned at the ends thereof. As the slide proceeds on itscourse it successively engages the spur gear 7 3 on its lower side whichlatter pushes the folding plates 74 one half of the distance across theends of the package and at the same time, the points on the slide haveadvanced one half the distance across the package from the opposite sidethereof, and during this same time the teeth 65 engage the gear 65 andpress the folder plates 61 and 64 down on the package. --During therotation of the shaft 77 the gear 40 is driving the gears 34 and 35 onecomplete turn each time. The paper is fed across the intacte table underthe feed hopper. and on the completion of the turn of the rollers 34 and35, the roller 44 strikes the lower end of the rod 48 and causes lthe-knife 48, to cut the paper. The spring 47 immediately4 returning theknife to the position shown in Fig. 1 after the'paper has been cut. Thecontinued movement of the shaft 77 returns the folding apparatus to theposition ini dicated in Fig. 1 and as soon as the shaft 77 is stopped inthat position, the gear teeth on the wheel 89 -come into Contact withthe teeth on the wheel- 88 and the latter is ro- \tated one completeturn, the link 92 pulling the plunger against the package and forcing:the fruit into the carton. The further gear 88 returns the plungerrotation of this .to the position s own in Fig. 3. v

1t will also be observed that the packages are moved forward one boxby'V the chain 105 which is driven by the gear 127. As soon as theplunger has been withdrawn from its travelaoross the weighing table, theweight causes the latter to rise and the bar 24 strikes thepin 21 andopens the feed gates allowing the fruit to again collect on the paperplaced vover the feed table. As soon as the shaft 58 has completed oneturn, the projection 123 throws the clutch points .122 and 121 out ofcontact and the machine 95 remains quiescent during the time the fruitis again collecting on the weighing table. rEhe cycle being carried outas often as a certain weight of fruit is placed on the weighing table.
